⚽️ 18x20x1 MERV 8 Furnace and A/C Air Filters

A MERV 8 filter catches the stuff you can see floating in a sunbeam: dust, pollen, lint, mold spores. It handles about 85–90% of particles in the 3–10 micron range. Excellent filters, I don’t need this level of filtration though. 6 filters Cash preferred https://www.furnacefilters.ca/products/18-x-20-x-1-merv-8-pleated-filters-case-of-12-48-00?_pos=1&_sid=440cfb5b8&_ss=r
